of or pertaining to anything of the douche related industry, ie hairstyle, clothing, etc. not to be confused with douche bag... d baggy is more of an insult, coined by the infamous Katie D in 2007, "d baggy" used to describe something that person wears or has on them rather than the person himself. It's just a better way of saying something about someone is exceptionally lame.

Blake, from American Idol, has the most D baggy haircut. Someone kick him off the show now.
